The Optimization of Savonius Helix Wind Turbine Cut-in Speed with the Variation of Blades-twist Rotor and Number of Blades

JIPTEK: Jurnal Ilmiah Pendidikan Teknik dan Kejuruan, 2023
Wind turbines are typically classified as Horizontal Axis Wind Turbines (HAWT) or Vertical Axis Wind Turbines (VAWT). VAWT has a superior ability to accelerate from rest to rotation than HAWT, allowing it to rotate the rotor even when the wind speed is ...

Experimental Study on the Performance of Three Vertical Axis Hydrokinetic Turbines

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Vertical‐axis hydrokinetic turbines have shown remarkable potential as a renewable energy option. However, their hydrodynamic performance remains uncategorized under turbulent, sedimented river flow conditions. This study presents a thorough and systematic experimental investigation to understand the impact of induced flow dynamics on three primary ...

Investigating the Effects of Air‐Jet on the Performance of a Hybrid Darrieus–Savonius Wind Turbine

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The power performance of a hybrid three–bladed H‐Darrieus turbine and a two‐bladed Savonius turbine is analyzed by adding air‐jet deflectors. Aluminum is selected for the blade design due to its high strength, lightweight, and corrosion resistance. Experimental analyses were conducted using the developed prototype with and without an air jet in an open
